A recently completed aerial survey of moose in northeastern Minnesota indicates the rate of population decline has accelerated dramatically.

The Minnesota Department of Natural Resources announced Wednesday that the northeast population declined 35 percent from last year. Since 2010, the moose population has declined 52 percent.

In response to the survey results, the DNR will not open a 2013 state moose hunting season or consider opening future seasons unless the population recovers.

“The state’s moose population has been in decline for years but never at the precipitous rate documented this winter,” said Tom Landwehr, DNR commissioner. “This is further and definitive evidence the population is not healthy. It reaffirms the conservation community’s need to better understand why this iconic species of the north is disappearing from our state.”

Landwehr stressed the state’s limited hunts are not the cause of the population decline. “Yet taking this action is reasonable and responsible in light of latest data and an uncertain future,” he said

Based on the aerial survey conducted in January, the new population estimate is 2,760 animals, down from 4,230 in 2012. The population estimate was as high as 8,840 as recently as 2006.

“It’s now prudent to control every source of mortality we can as we seek to understand causes of population decline,’’ said Landwehr.
Starting in January, wildlife researchers began fitting 100 moose in northeastern Minnesota with GPS tracking and data collection collars. This multi-year research project will investigate the causes of adult moose mortality, calf mortality, calf survival, moose use of existing habitat and habitat quality.

To date, 92 collars have been placed on moose in the Grand Marais, Ely and Two Harbors areas.
